Under Construction: Governor Harry W. Nice Memorial/Senator Thomas "Mac" Middleton Bridge Replacement

Cost and schedule ►

Public outreach ►

The Maryland Transportation Authority (MDTA) recently opened the replacement Governor Harry W. Nice Memorial/Senator Thomas "Mac" Middleton Bridge, which carries Route 301 over the Potomac River between Charles County in Maryland and King George County in Virginia.

The new four-lane bridge opened to traffic on Wednesday, Oct. 12, 2022. Construction began in July 2020.

Virginia contributed $13 million to the Maryland Transportation Authority project to widen and align Route 301 with the new bridge.

Additional work remains to be done on the project, including installation of dynamic message signs, a virtual weigh station, a weather station, some cameras, and the push button/warning beacon system bicyclists will use when crossing the new span. Lane sharing for bicyclists will be available after this system is installed and operational, anticipated in early 2023.

Please visit the MDTA's New Nice-Middleton Bridge Project page for additional information.


The bridge replacement widened the Route 301 bridge to four travel lanes.
